The Bloodied Black Heart

Jake Armstrong wants to find the person who has his wife’s donated heart. He meets Becky Rackley and believes she is that person. She thinks the same, but they don’t discuss it. Becky is a spy, and is on a mission to stop terrorists targeting a nuclear device on London. When the terrorists set an ultimatum, Jake is dragged into a world crisis where he will die unless Becky acts to save him.
By the time Becky gets to Moscow, Jake has disappeared and London has been evacuated with only a few days left before the terrorists carry out their threat to raze the city to the ground. MI5 believe Grigoriy Nabutov knows the location of the terrorists’ missile launch pad, and they order Becky to sleep with him to obtain the information. She baulks at their instruction, but realises it is the only way she might save London and find Jake, dead or alive.
